<P CLASS=para>
To create a container with no layout manager, use <tt CLASS=literal>null</tt> as the argument 
to <tt CLASS=literal>setLayout()</tt>. If you do this, 
you must size and position every component individually. In most cases, 
disabling the <tt CLASS=literal>LayoutManager</tt> 
is a bad idea because what might look great on one platform could look 
really bad on another, due to differences in fonts, native components, 
and other display characteristics. <A HREF="ch07_09.htm#JAWT-CH-7-FIG-13">Figure 7.13</A> displays 
a container with a disabled <tt CLASS=literal>LayoutManager</tt>; 
both buttons were positioned by specifying their size and location explicitly.

Here's the code that produces <A HREF="ch07_09.htm#JAWT-CH-7-FIG-13">Figure 7.13</A>:

<DIV CLASS=screen>

import java.awt.Button;
import java.applet.Applet;
public class noLayout extends Applet {
    public void init () {
        setLayout (null);
        Button x = new Button ("Hello");
        add (x);
        x.reshape (50, 60, 50, 70);
        Button y = new Button ("World");
        add (y);
        y.reshape (100, 120, 50, 70);
